Analysis of the Relationship Between the Recent Major Earthquake in Yunnan and the Position f Celestial Objects

After the three major earthquakes which happened in Menglian on July 12, 1995 with magnitude 7.3, in Wuding on October 24, 1995 with magnitude 6.5, and in Lijiang on February 3, 1996 with magnitude 7.0 respectively we calculated the position of celestial objects in solar system when the earthquakes happened and the astronomical singularities in two days before the event and in two days after the event. Besides the eruption of the three events were on the fullmoon or new moon, the concentrated occurrence of astronomical singularities has their outstanding characterisiccs. There were 8-10 astronomical singularities in the five days for each event, and there were 5-6 the oppsitions and conjunctions of the moon and planents. The zenith distances of the sun, moon and several planets were in the range 20 away from 90, therefore the vertical component of tide-generating acceleration were all direct to geocentre. The azimuth of the sun, moon and more than 4 planents were almost located at same plane, this is advantage for trigger of event.
